IM PROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 205,552, dated July 2,1878; application filed October 22, 1877.

To all whom it may concern Be it known that I, CHARLES E. HUNTER, ofFredericksburg, Spottsylvania county, Virginia, have invented anImprovement in Flows; and I do hereby declare the following to be a fulland correct description of the same, reference being had to theaccompanying drawings, in which- Figure 1 is a perspective view of myplow complete. Fig. 2 is a side view with the share or point and thecutting-front of the mold-board detached. Fig. 3 is a rear view, andFig. at a side view.

My invention relates to the construction of a plow; and it consists incasting the parts in pieces of the shape and configuration hereinafterdescribed, especially the standard, to which all the other pieces aresecured by bolts, forming a light, durable, and easy draftplow.

In the drawings, A represents the beam of aplow, to which the standard Bis secured by a cuff and wear-iron. The standard B consists of thebackwardlyinclined arm 1), extending against the side of the beam, and alip, 1), extending under the beam to support it.

Upon the standard B is the flange B, extending nearly to the bottom ofthe plow, and near the bottom is a projecting point, d, into which theshare D is locked. The front edge of the standard B is curved forwardhorizontally some distance below the beam, even with the top of themold-board, as at 111, when it again descends in a slight curve, similarto the first, nearly to the bottom of the plow. The front edge of thestandard is intended to be a uniform curve, except as it diverges toaccommodate the under inclination of the land-side, and is intended tosupport the land-side G and share D. Upon the rear of the standard B isanother projecting point, j, which catches into a similar dovetail inthe land-side.

The mold-board O and O is cast in two pieces, joined together by theangular line 0. Each piece is separately bolted to the standard B, aslight shoulder fitting over its front edge.

The share D, with a similar shoulder, is

bolted to the standard B, and near its middle locks into the point f.

Near the rear of the land-side is a flange, 6, simply for a support forthe handle of the plow. (Not shown.)

In the configuration of the plow, as a whole, the extreme point of theshare and the extreme rear of the land-side are lower than the pointwhere these parts join,making a suction in the draft, by which thefriction is lessened and the draft of the plow lessened and steadied. Asimilar suction is made on the land-side for a similar purpose. 7

An advantage of my invention is, that the draft is in line with thecenter of the resistance.

It will be observed in Fig. 3 that the standard B is perpendicular fromthe top of the land-side to the side of the beam, and that a shoulder orsudden curve, n, in the standard throws the top of land-side outward,and that the point and cutting-edge of the mold-board are in line withor outside of the beam, making the draft central and steady.

Having thus fully described my invention, what I claim is 1. Thestandard B of a plow, having the curve n, horizontal projection m,flange B, and point (1 upon said flange, as and for the purpose set forth.

2. The standard B, as described, having the flange B and the projectionm, curved toward the land-side, to form a face for the mold-board, incombination with the mold-board, cast in two pieces, 0 and C, said partsbeing united by an angular joint, and secured directly to the standardby bolts, substantially as described.

3. The standard B, provided with aperpendicular part and curve, n, incombination with the under inclined land-side E, substantially asdescribed.

The above specification of my said invention signed and witnessed, atFredericksburg, this 15th day of October, A. D. 1877.

CHARLES E. HUNTER.
